Abstract
Procedure for the preparation of alcoholilophyllines of the general formula **(See formula)** where R1 is hydrogen, or a methyl radical, R2 and R3 which may be the same or different, mean hydrogen, methyl, hydroxy or hydroxymethyl groups, R4 is hydrogen or a methyl group, and R5 is hydrogen or an alcohol group with 1 to 6 carbon atoms, a phenyl alcohol group with 7 to 12 carbon atoms or the group -NR6R7, where the radicals R6 and R7 are the same or different and represent hydrogen or alcohol groups with 1 to 6 carbon atoms, or together with the nitrogen atom form a 5-7 membered ring, which may optionally contain another oxygen, nitrogen or sulfur atom and may also be substituted by one or two alcohol groups with 1 to 4 carbon atoms and where, if R5 is hydrogen, also R1 is hydrogen and R2 means a hydroxy group in position 4, R3 means a methyl or oxymethyl group in position 3, R4 means hydrogen or a methyl group in position 5, and the straight propylene chain can ta also be substituted by alcoholic groups with 1 to 3 carbon atoms, and their salts by addition of acid, characterized in that a compound of the general formula is reacted **(See formula)** with a compound of the general formula **(See formula)** where Y is an oxygen atom or the hydroxy group plus a hydrogen atom, and X and Z are in each case different and signify either a halogen atom or an amino group, and X, if Z is a amino group and Y is a hydroxy group plus hydrogen, together with this hydroxy group can also form the ethylene oxide ring, and in the obtained compounds a keto group present is reduced to form the hydroxy group, and eventually the bases obtained are transformed into acid addition salts.
